2. The worker knows that the lower crate has a
mass of 50 kg and the upper a mass of 10 kg.
She finds that if she pulls with a force of 120 N
at an angle of 60° she can keep the crates
sliding at a constant speed. Can you use this
information to find the coefficient of friction
between the lower crate and the floor? If you can, do it. If you can't,
explain why not.
